Dunaliella is a green algae, a single-cell organism that is able to survive in extreme conditions of heat and salinity. As a means of coping with the harsh environmental conditions, the Dunaliella cell produces materials that help it survive. Those same materials can assist in rejuvenating human skin. These materials are using in the toiletry, cosmetic and skincare industries. Some of the algae ingredients are useful in creams toiletries. The Dunaliella was discovered by Michel Félix Dunal in 1838.
The Dunaliella can be found in Israel, Italy, France and other countries. It can be found in lakes, pools, lagoons and other bodies of water that contain either salt or fresh waters. The algae can survive in at sea and even at the Dead Sea, despite its name. When stimulated, the algae secretes beta-Carotene, which is used as a source of vitamin A in the human body. This vitamin has an essential role in the proper functioning of the skin. In addition, it is also the source of retinoid, whose derivative, the retinoic acid is used as a powerful anti-aging agent, and even as a cure for acne psoriasis.
Why is Dunaliella such a good source of beta-Carotene? Besides the favorable chemical form of the beta-Carotene extracted for the algae, it turns out that algae that were bred in conditions of high radiation and other stress factors, contain a higher percent of beta-Carotene. While algae bred in normal conditions contain only 0.3% beta-Carotene, those bred in conditions of high radiation and existential stress increased to ration of beta-Carotene to 10% of their dry weight. This substance facilitates the survival of the algae and protects it from solar radiation.
Scientific trials found that algae extracts improve skin metabolism, nourish it with vital substances, retain skin moisture even under extreme conditions, protect it from damage caused by environmental factors (radiation and heat), and slow the aging of the skin.
As a means of coping with harsh environmental conditions the Dunaliella cell produces materials that help it survive, which are also extremely helpful in rejuvenating human skin – proteins, polysaccharides, lipids, fatty acid, glycerol, vitamins, thiamine, pyridoxine, riboflavin, nicotinic acid, biotin, and vitamin E (tocopherol). Thanks to the substances found in its cells, the algae is considered as having special qualities, and is used in the toiletry and cosmetic industry.
